Abishek,

I don't believe JDK 7 is supported by DSpace at the moment.
Use the following link to acquire JDK6u31.

Hi Abhishek,

It looks like you are using the GNU libgcj version of Java.  DSpace requires 
the use of the Sun / Oracle JDK.  Swapping to the Sun / Oracle version might 
help with this problem.

Thanks,
